Allan Adams: The discovery that could rewrite physics
On March 17, 2014, a group of physicists announced a thrilling discovery: the “smoking gun” data for the idea of an inflationary universe, a clue to the Big Bang. For non-physicists, what does it mean? TED asked Allan Adams to briefly...

A Cancer Gene May Be More Friendly Than We Thought | SciShow News
Until now, researchers have assumed that healthy cells switch off the enzyme telomerase as a way to protect themselves from turning cancerous. But a new study suggests the enzyme may have a healthier role than we previously thought....

Wave Function
In this video Paul Andersen explains how the location of matter can be determined at the nanoscale using the wave function. The absolute value of the wave function can be used to determine the probability of finding matter in a location....

Wave-Particle Duality - Part 1
In this video Paul Andersen explains the wave-particle duality discovered by scientists. In certain situations particles (like electrons and photons) display wave like properties. This phenomenon can best be explored using the double...

3 Surprising Things That Act Like Fluids
Sometimes being in a traffic jam can feel like being stuck in a clogged pipe. And it turns out, maybe that feeling isn’t too far off. Today we look at 3 things that are remarkably unlike fluids, yet still behave in liquid-like ways.

How does ultrasound work? | Jacques S. Abramowicz
In a dark cave, bats can't see much. But even with their eyes shut, they can navigate rocky topography at incredible speeds. This is because bats aren't just guided by their eyes, but rather, by their ears. It may seem impossible to see...

Wavelength
In this video Paul Andersen explains how the wavelength is the distance between oscillations in a wave. In a longitudinal wave this might be the distance between areas of compression. In a transverse wave it might be the distance between...

TED-Ed: What’s a squillo, and why do opera singers need it?
An orchestra fills an opera house with music, but a singer’s voice soars above the instruments. Its melody rings out across thousands of patrons— all without any assistance from a microphone. How is it possible that a single voice can be...

TED-ED: How do we study living brains? - John Borghi and Elizabeth Waters
As far as we know, there's only one thing in our solar system sophisticated enough to study itself: the human brain. But this self-investigation is challenging because a living brain is shielded by skull, swaddled in tissue, and made up...
